SHUK-ABSORBER FOR VEHICLES.

Specification of Letters Patent.

- Application led May To all it may concern:

'Be it known' that L FRANK G. Kommen, a citizen of the United States of America,

tesiding at the city of St.. Louis, in the State of Missouri, have invented certain new and. useful Improvements in Shock-Absorbers for Vehicles, of which the following is o full; clear, and enact'description, reference being had tothe accompanying drawing, torming port of this specification.

My invention relates to that'character ot devices utilized in vehicles for the purpose ot minimizing the shock transferred fromy the @round Wheelsl of the vehicles -to the r body frames thereof.

Figure t is in part un elevation und in part a vertical longitudinal section of a spring 7.

oi the bell. crank levers is provided with e vehicle havin my shock absorbing devices incorporated t erein. Fig. H is an enlarged vertical transverse section taken on1ne mail, Fig. I. Fig. lll is an enlarged horizontal seetion taken on line lll-"JILL Fig. I. Fig. IVis an enlarged vertical longitudinal section of one-ot my shock absorbers together with a portion of the `trarne and aXle of n vehicle to which it is applied. Fig. V is a side elevation of a portion of. a vehicle Iframe and axle, showing my shook absorber, in :i slightly modified secured to the axle of thevehicle.

3 designate bell crank levers pivotally supported by the hanger 1. Une of the arms oi each of these 'bell crank leversis provided with a pocket to receive one end yof a main s ring 4, secured thereto by a U-shaped bolt', t e other or outer end of said spring being connected to a link 5, pivotally mounted Within a bifurcated end ofthe cross bar Q. The other member of each of the bell crank levers 3, which are preferably op-4 pronirnstelyf' vertically disposed, is providedwith. e'cnprsbnped spring seat socket 6, de-

signed to-receive an end of a compression Each of the sprung seat sockets screw thread-perforation ti, engaged by holL Patented Deo. 28, 1909.

low adjusting screws 9, having rounded in# ner ends vagainst which tit spring sent washers. ,l

11 designates draw tods which pass through Vthe hollow adj listing 'screws f l). and,L

sov

through the compression spring 7, said rods being Joined nttheii inner' ends b v interf V locking eyes. y

12. designates take-up sp1ings-a1rm1ged outside of, Aund. beitring againsto the cup shaped spring seat sockets ot1 the bell crunk levers 3, said' springs being positioned around the protruding ends of the adjusting 4screws 9- and rods 11.

13 designates spring seat caps having threaded engagement with the ,outer screw threaded l nds of the draw rods 11, and are designed t act as seats for the outer ends ot' the take-up springs 12 and upon `proper manipulation of these caps, the tensionde- 'sired on said springs mny be varied; The

spring seatcaps 13 are locked in the position desiredby suitble jam nuts 14 as is clearly illustinted'in' Fig'. IV of the drawings. f 4

VThe hollow adjusting screws f) are each provided with a wrench seat whereby they may be rotated to adjust the spring sent washers 10 and thereby produce more or less tension on the compression spring The .spring 7 acts'in compression v'and serves to carry the load of--the ninchiue'while the springs 1Q are more trike-up or cushion springs and act to cheek any rebound that there may be. The nuts 14 and cops lffl'hnvc nothing to do with confining the compressionspring 7 and even if they should be-, conie lost the machine would still be in good running` condition.

15 designates a 'guide and brace member' bolted or otherwise secured to the frame A,

said member being provided Wit-ha vertical slot' 16 in which operates a stud 17 carried by thecross bar 2, and by which construetlon approximately vertical alinernent between t e ground wheeland the vehicle body frame 1s maintained.

ln the modified form of the invention illustrated in Fig. V of the drawings, it will be observed that I have dispensed with the laminated springs, and have formed one of themembers 4" of eachl of the bell crank levers 3 of suiiicient length to pivotally engage the links 5. kIn other respects the .construction of the shock absorber is 'precisely like that of the construction previously described and wherein like arts bear like reference 'characters to said reviously described parts, but having su X primes.

I claim: Y

1. In a shock absorbing device, the combination with a vehicle body and axle, of a hanger carried by said body, bell crank levers pivotally connected to said hanger, a support carried by said axle, links pivotally connected tb said support and to which links one arm of each of the bell crank levers is pivotally connected,` and resilientmeans interposed between the other armsof said bell crank levers, substantially as set forth.

2. In a shock absorbing device, the combination with a vehicle body and axle,"of a hanger carried by said body, bell crank levers pivotally connected to said hanger and each having an arm of resilient material, a support carried by said axle, links pivotally connected .to said support and to which links the said Aresilient arms are. pivotally connected, and resilient means interposed between the other arms of said bell crank `levers, substantially as set forth.

3. Inra shock absorbing device, the combination with a vehicle body and axle, o" a support carried by said axle, links pivotally connected to said support, bell crank 'levers pivotally supported .by said vehicle body, one arm of each of said bell crank levers being pivotally connected to said links, resilient means interposed between the other arms of said levers, a rod extending through the said resilient means and arms, resilient means located to the outside of said arms and .surrounding said rod, spring seat members carried by said rods and which bear against the ends `of said last mentioned resilient means, and means for retaining said spring seat members in a desired position, substantially as set forth.

4. In a shock absorbing device for vehicles, the combination With a vehicle body and axle, pivoted bell crank levers, body carrying springs connected to said bell crank levers, a compression spring located between those ends of the bell crank levers that are @4a-,eve i not attached to the body carrying springs, and screwspassing through said bell crank levers and having seats on, their inner ends that bear against said'compression spring,

with said bell crank levers and having seats.

on their inner ends that bear against the compression spring, and a rod having nuts on its outer ends and which passes through said cushioning springs, through they bell crank levers, through the hollow screws and through the compression spring, substanjtially as set forth.

6. In a shock absorbing device, the combination with a vehicle body and axle, oit a support carried by said axle, links pivotally connected to said support, bell crank levers pivotally supported by said vehicle body, one arm of each of said bell crank levers being pivotally connected to said links, resilient means interposed between the other' arms of said levers, means for adjusting the tension ot' said resilient means, a rod extending through the resilient means and through said arms, resilient means located to the out'- side of said arms and surrounding said rod, spring seat members carried by said rods and which bear against the ends of said last mention resilient means, and means for adjusting said spring seat members on said rods to regulate the tension of said last mentloned resilient means, substantially as set forth.
